LONDON, May 29 (Reuters) - Rising steel prices in China helped to boost steelmaking ingredients zinc and nickel on Tuesday despite a stronger dollar making metals more expensive for buyers with other currencies.
China is the world's biggest steel producer and a seasonal recovery in construction activity has driven prices higher, with steel product rebar up 15 percent since late March.
"The stainless cycle is looking a little bit better," said BMO Capital Markets analyst Colin Hamilton. "I can see them (nickel and zinc) being supported."
NICKEL: Benchmark nickel on the London Metal Exchange was up 0.6 percent at $14,870 a tonne by 1042 GMT, taking gains since the start of May to almost 10 percent. Nickel on the Shanghai Futures Exchange hit three-year highs on Tuesday.
TECHNICALS: Technical resistance was at Friday's high of $15,055 and profit-taking around the $15,000 mark was making it harder for prices to move higher, broker Marex Spectron said.
ZINC: LME zinc was up 1.1 percent at $3,084.50 a tonne. The metal has fallen 14 percent from a 10-1/2 year high in February but was threatening to break above its downtrend line on Tuesday, which could trigger technical buying.
STOCKS: On-warrant zinc inventories available to the market in LME-registered warehouses fell 9.2 percent to 195,325 tonnes, suggesting a tighter market and supporting prices. However, stocks are still far from April's low of 139,450 tonnes. <MZNSTX-TOTAL>
CHINA FACTORIES: Underpinning a strong demand outlook for metals, growth in China's vast manufacturing sector is expected to have dipped marginally in May.
CHINA POLLUTION: Eight Chinese regions have promised to beef up anti-pollution curbs. A crackdown on polluting industry in China cut metals production capacity last year, helping to lift prices.
DOLLAR: The dollar extended a six-week rally, strengthening to a 2018 high against a basket of major currencies.
INDIA COPPER SMELTER: An Indian state ordered the permanent closure of the country's second-biggest copper smelter, which produces more than 400,000 tonnes of copper a year. There was no strong price reaction, with LME copper down 0.1 percent at $6,881 a tonne.
TIN: LME tin was 2.5 percent higher at $20,660 a tonne after last week hitting its lowest since January. Traders said the market was concerned that shipments from China's top supplier Myanmar were falling.
ALUMINIUM PREMIUMS: A global aluminium producer has offered Japanese buyers a premium of $159 a tonne for primary metal shipments for the July-September quarter, up 23 percent from the current quarter, sources said.
OTHER METALS: LME aluminium was down 0.2 percent at $2,259 a tonne and lead gained 0.3 percent to $2,445.
